Fine Particulate Matter level due to conditions favourable to ozone formation, such as
wildfire smoke under sunny, warm conditions.
Fine particulate matter (PM2.5) refers to microscopic
particles that are 2.5 micrometres or smaller in diameter.
Major sources in B.C. include residential wood combustion,
prescribed burning, marine vessels, heavy-duty diesel
vehicles, the pulp and paper sector, and the mining
sector. Travelling deep into the lungs, inhaled PM2.5 can
cause short term health effects such as irritation and
inflammation and can aggravate health conditions such as
asthma and heart disease. There is strong evidence that
prolonged exposure to PM2.5 increases the risk of chronic
disease, such as bronchitis and heart disease.3
In 2019, PM2.5 was monitored at more than 60 sites across
the province for at least a portion of the year. Annual
average concentrations ranged from 2.0 µg/m3 in Powell
River-J Thomson to 10.6 µg/m3 in Houston. A total of 7
sites exceeded the provincial annual objective of 8 µg/
m3 and 3 exceeded the provincial 24-hour objective of 25
µg/m3. 4 These are down from the previous year where
19 and 24 of the sites exceeded the annual and 24-hour
objectives, respectively. The elevated PM2.5 levels for 2019
were concentrated in the cold months during periods of
stagnant weather, particularly February, when outbreaks of
Arctic air produced historic low temperatures across B.C.
